The opening and closing part of the back pressure valve is a disc-shaped valve plate, which rotates around its own axis in the valve body, so as to achieve the purpose of opening and closing or adjustment. What are the precautions for back pressure valves? Let’s take a look together:
There are six points for attention of the back pressure valve:
1. Avoid resonance with the system.
2. When used together with the pulsation damper, the pulsation damper should be installed between the pump and the back pressure valve to absorb the flow peak between the pump and the back pressure valve. Slow down the wear rate of the back pressure valve.
3. For outdoor use, a protective shed or protective cover should be added.
4. Before performing any maintenance on the back pressure valve, stop the equipment, release the pressure, close the valve connected to the back pressure valve and the system, and confirm that there is no pressure in the pulsation damper. Pay attention to prevent the liquid being transported from harming the human body during maintenance.
5. If the inlet and outlet of the back pressure valve are reversed, the back pressure will increase exponentially, which will bring harm to the system and may cause danger.
6. If the back pressure valve fails during operation, the power supply should be cut off in time.
What needs special attention here is that before any maintenance on the back pressure valve, the equipment should be stopped, the pressure should be released, the valve connected to the back pressure valve and the system should be closed, and at the same time, it should be confirmed that there is no pressure in the pulsation damper. Pay attention to prevent the liquid being transported from harming the human body during maintenance.
The above six points are the precautions for the back pressure valve that I will share with you today, so hurry up and get up~
